Moon's debut single "Million" contains the female singer's vow to work hard and stay dedicated to her work, unlike those who only talk about their goals, never taking action. The track was written and composed by Moon herself, and she also showcases great musical chemistry with featuring artist Dok2 in the MV above.

Million Market, home to hip-hop and R&B artists including Woo Taewoon, Chancellor, PENOMECO, and more, recently became a subsidiary of SM Entertainment earlier this month as SM became the company's largest shareholder. Watch Moon's debut MV above.
